A high-precision inductor processing device and method

Abstract

The invention discloses a processing device and method for a high-precision inductor. The method comprises the following steps: 1, winding a copper coil (1); 2, assembling the copper coil well wound in the step 1 with casings (2); 3, winding a magnetic core in the casings (2). Winding of a magnetic strip is controlled through a rotatable part in the casings (2), so that the rotatable part is matched with inductance measurement equipment, connected with the copper coil (1), to measure the inductance value, when the inductance value meets the requirement, the rotatable part is stopped, and production of the inductor is finished. Electrical parameters of the inductor have high consistency, meanwhile, use of an inductor with a large wire diameter is not dependent on manual operation any more, and the production efficiency and the product quality are improved greatly.

Description

technical field

[0001] The invention relates to a processing method and device for ring inductors, especially a method and device capable of automatic processing while realizing precise control of inductance. The invention can be used for common mode inductors (double windings), differential mode inductors (single winding ) and ring transformer (multi-winding) processing. Background technique

[0002] The processing of existing ring inductors mostly relies on manual and automatic winding machines to process and wind enameled wire coils, but the above-mentioned processing technology is powerless when faced with the processing of ring inductors with a wire diameter above 0.5mm, and cannot break through the size limit. On the other hand, considering the deviation of the finished product due to the processing technology and material of the magnetic material itself, usually about 20%, it is necessary to design a device that can automatically process high-precision ring inductors....
